Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical technology, specifically a rapid energy storage and release mechanism. Background Technology

[0002] Miniature circuit breakers or switchgear have both manual and electric operation modes. When closing, the contact system performs the closing operation synchronously with the speed of operation.

[0003] In the prior art, such as the application with application number 2017211704178, the subject of which is: a quick closing mechanism for a disconnecting switch, including an energy storage spring, a limiting member, and a torsion spring, when the drive seat rotates with the handle in the closing direction, the limiting protrusion on the drive seat slides into the energy storage limiting groove and stores energy in the energy storage spring. When the handle drives the drive seat and unlocks the limiting member, the limiting protrusion on the drive seat slides onto the energy release guide surface and releases energy in the energy storage spring, and the drive seat can quickly rotate to the closing position.

[0004] However, in the existing technology, such as the fast closing mechanism mentioned in application number 2017211704178, when there is a large power load in the circuit and the expected operating current is large, closing will cause the arc generated by the circuit breaker contact system to cause electro-corrosion. The long closing time will affect and shorten the equipment life. At the same time, because the actual current is small and the power provided is insufficient during the closing process, it will also damage the electrical equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid energy storage and release mechanism to solve the problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0014] Preferably, one end of the incomplete gear is provided with a fixed rotating wheel, and one end of the fixed rotating wheel is fixedly provided with a round shaft two.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] A fast energy storage and release mechanism, such as Figure 1 As shown, the rapid energy storage and release mechanism includes a first bracket 1, a second bracket 6, and a third bracket 13. A transmission wheel 3 is provided between the first bracket 1 and the second bracket 6, and an incomplete gear 12 is provided between the third bracket 13 and the second bracket 6. A square shaft 4 is provided through the second bracket 6.

[0030] like Figure 2 As shown, bracket 1 has a shaft hole 101, bracket 3 has a shaft hole 131, and transmission wheel 3 has a connecting hole 34. A U-shaped lever 2 is rotatably connected to the connecting hole 34. A small circuit breaker or switchgear using the fast energy storage and release mechanism is connected through the U-shaped lever 2. The two ends of the U-shaped lever 2 are bent into connecting rods 21, which are connected to the connecting hole 34 by plugging.

[0031] A through hole is provided on the second bracket 6, and the square shaft 4 is rotatably installed in the through hole. A pad is fixed on one side of the second bracket 6, and the pad is provided with an opening groove.

[0032] One end of the transmission wheel 3 is rotatably connected to the shaft hole 101 on the bracket 1 via a round shaft 31, and a reset torsion spring 5 is fixedly installed between the other end and the bracket 6.

[0033] One end of the incomplete gear 12 is rotatably equipped with a fixed rotating wheel 7. One end of the fixed rotating wheel 7 is fixedly connected to a round shaft 74. The round shaft 74 passes through the incomplete gear 12 and is rotatably connected to the shaft hole 131 on the bracket 13. The square shaft 4 is used to connect the transmission wheel 3 and the fixed rotating wheel 7. An energy storage torsion spring 11 is provided on the round shaft 74. One end of the energy storage torsion spring 11 is fixedly equipped with a bent rod 111, and the other end is fixedly equipped with a straight rod 112.

[0034] like Figure 3 , Figure 5 As shown, a latch 8 and a latch spring 9 are rotatably installed on one side of the fixed rotating wheel 7. A square hole 72 is opened on the end of the fixed rotating wheel 7 away from the round shaft 74. A connecting hole 73 is opened on the fixed rotating wheel 7. The bent rod 111 is inserted and fixed into the connecting hole 73. The square hole 72 is inserted and fixed into one end of the square shaft 4. A hook 71 is fixedly provided on one side of the fixed rotating wheel 7.

[0035] The latch 8 has an arc-shaped structure. A protrusion 82 is fixedly provided on one side of the latch 8, and the other side abuts against one end of the latch spring 9. The latch spring 9 presses the latch 8 against the fixed rotating wheel 7. The protrusion 82 is used to cooperate with the hook 71 to prevent the fixed rotating wheel 7 from rotating. An arc-shaped protrusion 81 is fixedly provided on the latch 8.

[0036] The arc-shaped protrusion 81 and the incomplete gear 12 are located on the same side of the fixed rotating wheel 7. The incomplete gear 12 is provided with several tooth blocks 121. An arc-shaped push block 122 is fixed on one side of the tooth block 121. The arc-shaped push block 122 cooperates with the arc surface of the arc-shaped protrusion 81, pushing the locking buckle 8 to rotate, compressing the locking buckle spring 9, so that the protrusion 82 of the locking buckle 8 is disengaged and separated from the hook 71 of the fixed rotating wheel 7.

[0037] like Figure 4 As shown, a square hole 33 is provided at the end of the transmission wheel 3 away from the bracket 1. The square hole 33 is inserted and fixed to the end of the square shaft 4 away from the square hole 72. A groove 32 is provided at one end of the transmission wheel 3. One end of the reset torsion spring 5 is engaged with the groove 32 and located in the open slot. The other end is connected to the bracket 6 to control the reset of the transmission wheel 3.

[0038] like Figure 6 As shown, the incomplete gear 12 has a through hole 124, which is used to rotatably connect the second round shaft 74. The second round shaft 74 passes through the through hole 124 and is connected to the second shaft hole 131. A slot 123 is provided on the incomplete gear 12 and on one side of the through hole 124. The straight rod 112 is connected to the slot 123 and is used for the rotation of the incomplete gear 12. Moving the straight rod 112 causes the energy storage torsion spring 11 to twist and store energy.

[0039] The working principle is as follows:

[0040] When the protrusion 82 on the latch 8 engages with the hook 71, the incomplete gear 12 is driven to rotate and the torsion spring 11 is torsionally stored to store energy. Then, when the arc-shaped push block 122 on the incomplete gear 12 pushes the arc-shaped protrusion 81 on the latch 8, the restriction between the latch 8 and the fixed rotating wheel 7 is released. At this time, the energy-storing torsion spring 11 releases the torsionally stored energy, drives the fixed rotating wheel 7 to rotate and drives the transmission wheel 3 to rotate via the square shaft 4. The transmission wheel 3 drives the U-shaped lever 2 to move, realizing energy transfer and rapid energy release.

[0041] When the arc-shaped push block 122 on the incomplete gear 12 moves past the arc-shaped protrusion 81, the locking spring 9 pushes the locking buckle 8 to continue to abut against the fixed rotating wheel 7 until the incomplete gear 12 rotates until the hook 71 on the fixed rotating wheel 7 abuts against the protrusion 82. At this time, the energy storage and release operation is performed again. In the above process, the output direction of the drive component that drives the incomplete gear 12 to rotate is always consistent, which makes driving convenient and energy storage and release rapid. There will be no excessively long opening and closing operation time, and no electric arc damage to the internal electrical equipment. Moreover, the rotation of the transmission wheel 3 connected to the square shaft 4 is adjusted by the reset torsion spring 5 to maintain the controllability and reliability of the rotation of the transmission wheel 3.
